Fix crash due to invalid timespec given to pselect
If blinktimeout is set to a value greater than 1000, pselect will receive a timeout argument with tv_nsec greater than 1E9 (1 sec), and fail, making st crash. This patch just ensures that the timespec structure is correctly filled with a value properly decomposed between tv_sec and tv_nsec. Reported by JasonWoof on IRC. Thanks!
